6. The ADBI-60 is powered by System MXL/MXL-IQ (Figures 5 and 6);
the System power for indicating appliances is 5A. If more than 5A is
required, use the configuration in Figure 3 or Figure 4 for auxiliary
power. See Note above.
7. Connect terminal 6 of the PS-35 (Figures 3 and 4) to the minus DC
side of the System XL3 or MXL/MXL-IQ main power supply for proper
ground fault supervision.
8. The ADBI-60 is powered by System IXL (Figure 7); the System power
on indicating appliances is 3A. If more than 3A is required, use the
configuration in Figure 8.
9. Each audible base is marked as follows to indicate its type (ADBI-60
or ADB-3):
Note:
For additional information on the modules used in an individual
system, refer to the Installation Instructions for that particular
module or contact your authorized Siemens Building Technologies,

DETECTOR PLACEMENT
The table at right lists the detectors that can be used with the ADB-3 and
ADBI-60 Detector Bases, along with the appropriate Installation Instructions.
Even though no specific spacings are allocated to the detectors used with
these bases, use 30 foot center spacing (900 sq ft), as referred to in NFPA
Standard 72 National Fire Alarm Code, Chapter 5 and CAN/ULC-S524, as a
guide or starting point, if practical, in a detector installation layout. This spacing
is based on ideal conditions—smooth ceiling, no air movement, and no physi-
cal obstructions.
In all installations (except in special circumstances like computer room
underfloors), locate the detector on the ceiling, a minimum of 6 inches from a
side wall, or on a wall, between 4 and 6 inches from the ceiling.
If questions arise regarding detector placement, it is extremely important that
the drawings provided or approved by Siemens Building Technologies, Inc. or
by its authorized distributors be followed! The detector placements shown on
these drawings were chosen after a careful evaluation of all facets of protecting
the area. Environmental factors such as air current, temperature, humidity, air
pressure, and the nature of the fire load are carefully considered. Special
consideration is given to room or area configuration and the type of ceiling
(sloped or flat, smooth or beamed). Siemens Building Technologies, Inc.'s
extensive experience in the design of fire detection systems assures optimum
detector placement and is reflected in these drawings. Follow sound engineer-
ing judgment made by qualified personnel.
